"The International" is returning yet another year. Valve's annual Dota 2 tournament will be held in Seattle on August 7th, a few weeks before PAX Prime.
So far, the only invited team is last year's winner: Invictus Gaming. Three teams will be invited based on East and West qualifying brackets, beginning May 13th.
